Looking for a 6 1/4 "or 6 1/2 " 4 groove crank pully.
Message me if you have one.Thanks
 
I have a 72 4 groove but it's 7-1/4" - matches up with the balancer for internal balanced crankshaft, not sure I've seen one that small, maybe aluminum aftermarket ? I have 1 more place I know I have some more pulleys, they're kinda buried but I'll check them asap

Sorry, Kim. Thank you for trying to help.I will respond to posts in the future, in a more timely manner
 
I may have another if u still need it, but I haven’t measured them yet. Kim
Thanks ,Kim.The situation is that I have a 7 1/4 crank pully.But the holes line up for all , but 1 that is just a little off.Something isnt right.I have a milk crate of different pullys I' ve been trying to match.Trying to figure it out....I may still need another 4 groove pully.Please dont exclude me while I do some research.Thanks again
 
The newer Dampers had equal spacing on the holes for the pulley. The older style had one hole offset. Not sure when the change was made. Some repop pulleys have an elongated hole which will work on either. I didn't find one that small of diameter, but I have a few at 7-1/4"
 
Not sure when they changed patterns, but I think for 1970 and up. U could just elongate the hole like the aftermarket did. Ms y ppl do that. Kim

I've done it before myself , just be careful and it will work just fine , I will still keep an eye out for others when I get to that container of pulleys for any smaller diameters
